'COLGR-MIXING DEVICE.

Application filed october 29, 1921. serialvrro. 511,516.

lTo all whom it may/concern:

Be it known that I, LYDA SUE BowER,

a citizen of the United States, residing at Covington, in the county ofNewton and State of Georgia, have invented new and useful improvementsin Color-MiXing Devices, and of which the -following is a speciication..f

This invention relates to color devices, particularly tov instruction orcomparing devices, and has for its ob'ect the provision of a motordriven device y means of which any and all shades of all colors may bequickly and easily produced for purposes of instruction in institutionsof learning and the like or for purposes of comparison in aint or dyefactories.

n important and more specific object is the provision of a novel holdingmeans adapted for association with the shaft of an electric motor orother rotary device, a plurality of disks of different colors beingdisposable upon this holding device and being secured thereon inadjusted position whereby certain cut-out portions of the ,respectivedisks may be brought or left to registration according to apredetermined plan whereupon subsequent rotation of the assembled diskswill, on account of the retention or continuance of vision, produce theeffect of a certain shade or color which is the composite of thosecolors upon the exposed portions of the colored disks.

Another object is the provisio-n of a device of this character includingnovel means whereby to clamp a plurality of certain disks upon theholding member, the clamping means being adjustable whereby to varyv thedegree of exposure of the successive disks.

An additional object is the provision of a mechanism of this characterwhich will be simple and inexpensive in manufacture, easy to use andoperate, highly efficient in action, durable in service and a generalimprovement in the art.

With the above and 'other objects and advantages in view, the inventionconsists in the details of construction to be hereinafter more fullydescribed and claimed, and illustrated in'the accompanying drawings inwhich,

Figure 1 is aside elevation of lmy vdevice associated with an electricmotor,\

Figure 2 is an endelevation,

Figure 3 is a longitudinal sectional view,

Figure 4 is a detail face view ofithe locking nuts,

Figure 5 is a detail elevation of one of the color disks and, i

Figure 6 is a detail view of the hook member.V

Referring more particularly to the drawings the letter A designates anelectric motor of any ordinary or'preferred type and B designates theshaft thereof.

In carrying out my invention l' provide a sleeve device 10 which isadapted to be engaged upon the shaft B andv which includes an elongatedthreaded portion 11, an annular flanged portion 12 and an eX- tension 13through which extends a plurality of set-screws 14 by means of which thesleeves may be clamped upon the shaft of the motor. It is preferablethat the threads upon the threaded portion 11 be comparatively coarsethough such is not absolutely essential as will be hereinafterdescribed. rlhe dimension of these parts is not essential as it isreadily apparent that they may be varied within wide degrees dependingupon the diameter of the shaft and the power of the motor withv whichthe device is associated. l

Designed to be engaged upon the threaded portionof this sleeve 10 is aseries of disks 15 which may be constructed of brass, tin, fibre orother suitable materi-al, these disks being provided centrally with ahole 16 and being provided with cut-out portions 17. The outer portionsof the disks are calibrated or graduated in fractions of inches or'incentimeters and meters as may be preferred, these graduations beingclearly indicated in the drawings and for a purpose to be described.

ln actual practice it is preferred to use about seven of these diskswhich are painted or otherwise colored with the colors of the solarspectrum, namely; red, orange, yellow, green, blue, indigo andfyviolet.

As stated above these disks 1'5 are designed to be placed upon thethreaded portion of the sleeve 10, any suitable number of the disksbeing employed as will be hereinafter described. It is of coursenecessary to rigidly secure the disks upon the sleeve and in order toeffect such action l make use of a nut member which comprises a collar18 internally threaded so as to be screwed upon the threaded portion 11ofthe sleeve 10 and proyided at its outer edge portion with an annularvflange 19 which is preferably knurled, filed or otherwise roughenedwhereby to provide an elicient grip to prevent slipping within the handof the operator. Rotatably mounted upon the intermediate portion of thiscollar 18 is a ring 20 whlch is designed to be locked in any desiredadjusted position with respect to the collar by means of a suitable setscrew 21. upon and extending outwardly of this ring 2O is a series 0fhook-shape members which are arranged at preferably equi-distant pointsalong the periphery of the rmg. rIhese hooks 22 are designed to engageagainst the edges of the cut-away portions 17 of the disks 15 whereby tohold the disks 15 against relatively rotation when they are secured uponthe sleeve.

In assembling my device it will be apparent that the sleeve 10 isdisposed upon the shaft B after which the set screws 14 are tightened tohold the sleeve securely with respect to the shaft so that when themotor is operated the entire sleeve and `associated parts will berotated. Depending upon the colors or shades to be displayed or seen,the selected disks 15 are placedupon the threaded portion 11 of thesleeve after which the nut member is threaded into the sleeve andscrewed up against the outermost disk, with the cut-out portions of thedisk arranged in more or less over lapping relation depending upon thedegree or area of the different successive colors to be displayed orexposed. The relative proportions of the different colors may of coursebe readily seen by means of the graduations upon the disks so that inthis way practically all shades may be easily obtained. It will be seenthat owing to the provision of the graduations that mathematicalprecision may be had as to the relatively areas or proportions of thedifferent colors. The hook members 22 carried by the ring 20 of courseengage against the edges of the cut-away portions of the disks. It willbe seen that owing to such engagement of the hooks with the edges of thecut-away portions of the disks, relative rotation of the disks withrespect to one another will be absolutely prevented while the engagementof the nut member with the outermost disk will hold all the disks firmlyassembled upon the threaded portion 11 of. the sleeve with one cndmostdisk engaged by the nut member andthe Iother endmost disk engagedagainst the flange 12 of the sleeve member 10.

In actual practice it may also be found advisabley to make use of aplurality of U- shaped spring clips 23 which naturally would be made ofdifferent sizes so that they might be engaged upon onl)T two disks,three disks or in fact the desired number of disks which might beemployed, these clips being clearly engaged over the outer Securedltated it will be apparent that my device will be rotated carrying withit all of the disk members. Owing to the fact that the disk members areprovided with cut-out portions which will more or less display certainareas of the disks next beneath, the different disks of course bengdifferently colored, it will be apparent that on account of theretention or continuance of human vision the rapid rotation of the diskwill result in giving the appearance of a single color. In this way itwill be quite obvious that the device is well adapted for use inschools, colleges and other institutions of learning whereby to acquaintthe pupils with the different color values and the proportions of thedifferent colors which go to make up the different shades and dilferentcombinations, the device also being readily capable of use in factoriesof paint manufactures, dye manufactures and others whereby to constitutea testing device for comparing -the newly made colors with certain wellknown standard dye shades so thatexact correspondence may be maintained.1

From the foregoing description and a study of the drawings it will beapparent that I have thus provided an extremely simple and consequentlyinexpensive device which is easily used and which may be associated withany ordinary or preferred type of electric motor regardless of thedetails of the latter, the device being furthermore capable of use inassociation with any sort of mechanism which will insure rapid andcontinual rotation of the element at a constant speed. It will beobserved that the device will be highly eflicient especially inasmuch asit requires no attention from the operator other than the initialsetting of the parts in While I have shown and described the l preferredembodiment of the invention, it is of course to be understood that Ireserve the right to make such changes in the form, construction andarrangement of parts as will not depart from the spirit of the inventionor 4the scope of the subjoined claims.

Having thus described my invention I claim 1. A color device of thecharacter described comprising an elongated sleeve member adapted to beclamped upon the shaft of a motor or other driven device, said sleevevmember being formed with an outwardly cxtending iiange and beingthreaded from said flange toits outer end, a plurality of selectivelyusable disk members cach having a. central hole engageable upon the'threaded portion of the sleeve and being provided with a cut-outportion extending from the outer edge to the hole, said disk membersbeing colored With the colors of the solar spectrum, a. nut memberthreaded upon said sleeve and engageable with the outermost disk memberto hold all of the disk members in clamping engagement with one anotheragainst said flange for preventing relative rotation of the diskmembers, and a pluraL ity of spring clips engageable upon theperipheries of said disk members for the purpose specified.

2. A color device of the character described comprising an elongatedsleeve member adapted to be clamped upon the shaft of a motor or otherdriven device, said sleeve member being formed with an outwardlyextending Harige and being threaded .from said flange to its outer end,a plurality of selectively usable disk members of 'different colors eachhaving a central hole engageable upon the threaded portion of the sleeveland being provided with a cut-out portion, a nut member threaded uponsaid sleeve and engageable With the outermost disk member and beingadapted to hold all of the disk members in clamping engagement with oneanother against said ange for preventing relative rotation of the diskmembers, said nut member comprising a eollar threaded upon the threadedportion of the sleeve, and a ring rotatably adjustable upon the collarand carrying a plurality of hooks engageable With the edges of theeutaway portions of the disks as and for the purpose specified.
